I apologize if I wasn't clear, simpsonqueen. KH told you that Digimon tend to have the same name, with simple prefixes before the name to decipher which is which. In actuality, the prefix thing applies mainly to champion, ultimate and mega digimon, and to a lesser extend, in-trainings to rookies.
Example: Greymon -> MetalGreymon -> WarGreymon
Example: DemiVeemon -> Veemon
I would appreciate (I apologize if I sound snippy) if you could possibly consider naming your champion digimon, and simply add prefixes to that for the ultimate and mega. As for the Baby form, if you could, make a completely new name, and make the in-training have a "demi-" or "ko-" prefix of the rookie's name. If I still confound you, please let me know.
